Precision Measurement of Microwave Comprehensive resource covering the foundations and analysis of precision noise measurements with a detailed treatment of their uncertainties Precision Measurement of Microwave Thermal Noise presents the basics of precise measurements of thermal noise at microwave frequencies and guides readers through how to evaluate the uncertainties in such measurement. The focus is on measurement methods used at the U.S. National Institute of Standards and Technology (NIST), but the general principles and methods are useful in a wide range of applications. Readers will learn how to perform accurate microwave noise measurements using the respected author’s expertise of calculations to aid understanding of the challenges and solutions. The text covers the background required for the analysis of the measurements and the standards employed to calibrate radiofrequency and microwave radiometers. It also covers measurements of noise temperature (power) and the noise characteristics of amplifiers and transistors. In addition to the usual room-temperature two-port devices, cryogenic devices and multiport amplifiers are also discussed. Finally, the connection of these lab-based measurements to remote-sensing measurement (especially from space) is considered, and possible contributions of the lab-based measurements to remote-sensing applications are discussed. Specific topics and concepts covered in the text include: Noise-temperature standards, covering ambient standards, hot (oven) standards, cryogenic standards, and other standards and noise sources Amplifier noise, covering definition of noise parameters, measurement of noise parameters, uncertainty analysis for noise-parameter measurements, and simulations and strategies On-wafer noise measurements, covering on-wafer microwave formalism, noise temperature, on-wafer noise-parameter measurements, and uncertainties Multiport amplifiers, covering formalism and noise matrix, definition of noise figure for multiports, and degradation of signal-to-noise ratio Containing some introductory material, Precision Measurement of Microwave Thermal Noise is an invaluable resource on the subject for advanced students and all professionals working in (or entering) the field of microwave noise measurements, be it in a standards lab, a commercial lab, or academic research.

Thermal noise from optical coatings is a growing area of concern and overcoming limits to the sensitivity of high precision measurements by thermal noise is one of the greatest challenges faced by experimental physicists. In this timely book, internationally renowned scientists and engineers examine our current theoretical and experimental understanding. Beginning with the theory of thermal noise in mirrors and substrates, subsequent chapters discuss the technology of depositing coatings and state-of-the-art dielectric coating techniques used in precision measurement. Applications and remedies for noise reduction are also covered. Individual chapters are dedicated to specific fields where coating thermal noise is a particular concern, including the areas of quantum optics/optomechanics, gravitational wave detection, precision timing, high-precision laser stabilisation via optical cavities and cavity quantum electrodynamics. While providing full mathematical detail, the text avoids field-specific jargon, making it a valuable resource for readers with varied backgrounds in modern optics.

A GUIDE TO NOISE IN MICROWAVE CIRCUITS A fulsome exploration of critical considerations in microwave circuit noise In A Guide to Noise in Microwave Circuits: Devices, Circuits, and Measurement, a team of distinguished researchers deliver a comprehensive introduction to noise in microwave circuits, with a strong focus on noise characterization of devices and circuits. The book describes fluctuations beginning with their physical origin and touches on the general description of noise in linear and non-linear circuits. Several chapters are devoted to the description of noise measurement techniques and the interpretation of measured data. A full chapter is dedicated to noise sources as well, including thermal, shot, plasma, and current. A Guide to Noise in Microwave Circuits offers examples of measurement problems—like low noise block (LNB) of satellite television – and explores equipment and measurement methods, like the Y, cold source, and 7-state method. This book also includes: A thorough introduction to foundational terms in microwave circuit noise, including average values, amplitude distribution, autocorrelation, cross-correlation, and noise spectra Comprehensive explorations of common noise sources, including thermal noise, the Nyquist formula and thermal radiation, shot noise, plasma noise, and more Practical discussions of noise and linear networks, including narrowband noise In-depth examinations of calculation methods for noise quantities, including noise voltages, currents, and spectra, the noise correlation matrix, and the noise of simple passive networks Perfect for graduate students specializing in microwave and wireless electronics, A Guide to Noise in Microwave Circuits: Devices, Circuits, and Measurement will also earn a place in the libraries of professional engineers working in microwave or wireless circuits and system design.

Measuring Ocean Currents: Tools, Technologies, and Data covers all major aspects of ocean current measurements in view of the implications of ocean currents on changing climate, increasing pollution levels, and offshore engineering activities. Although more than 70% of the Earth is covered by ocean, there is limited information on the countless fine- to large-scale water motions taking place within them. This book fills that information gap as the first work that summarizes the state-of-the-art methods and instruments used for surface, subsurface, and abyssal ocean current measurements. Readers of this book will find a wealth of information on Lagrangian measurements, horizontal mapping, imaging, Eulerian measurements, and vertical profiling techniques. In addition, the book describes modern technologies for remote measurement of ocean currents and their signatures, including HF Doppler radar systems, satellite-borne sensors, ocean acoustic tomography, and more. Crucial aspects of ocean currents are described in detail as well, including dispersion of effluents discharged into the sea and transport of beneficial materials—as well as environmentally hazardous materials—from one region to another. The book highlights several important practical applications, showing how measurements relate to climate change and pollution levels, how they affect coastal and offshore engineering activities, and how they can aid in tsunami detection. Coverage of measurement, mapping and profiling techniques Descriptions of technologies for remote measurement of ocean currents and their signatures Reviews crucial aspects of ocean currents, including special emphasis on the planet-spanning thermohaline circulation, known as the ocean's "conveyor belt," and its crucial role in climate change
